Influence of Natural Aggregates’ Mineralogical Composition on the Adhesiveness and Affinity of Bitumen
The paper presents the studies and the laboratory researches performed on two important factors that influence the durability of the asphalt mixture, namely the adhesiveness and affinity of bitumen to aggregates. To highlight the two characteristics, one bitumen grade (50/70) and natural quarry aggregates from five different sources were used. The experimental program consisted of determining the adhesiveness through the qualitative method (spectrophotometric method, nondestructive method) and the affinity through the rolling bottles method (destructive method), the main purpose of this study being to draw the attention to a possible link between these two methods. The results obtained vary from one aggregate source to another given the morphology and the physical-chemical properties of the aggregates. The research findings complete the picture of the factors that influence the adhesiveness and affinity of bitumen to aggregates and highlight the susceptibility to the stripping of binder under the humidity effect of the aggregate-binder bond.
